Introduction: The aim of this study was to determine the safety and efficacy of porous polyethylene sheet implants in the reconstruction of blow-out fracture without any fixation procedure. Methods: Patients who underwent orbita reconstruction using porous polyethylene sheets for the repair of orbital floor fracture were included in the study group. Indication for surgery were patients with enophthalmos, dystopia, limited ocular motility or diplopia on physical examination, fracture of the orbital floor, orbital entrapment or prolapse during computed tomography. Patients were retrospectively analyzed in terms of gender, age, mechanism of injury, concomitant fractures, surgical approach, follow-up period, time of surgery and complications such as diplopia, enophthalmos, dystopia, limitation of ocular motility and infra-orbital hypoesthesia. All statistical analyses were performed using IBM SPSS for Windows version 20.0 (IBM Corp., Armonk, NY, USA). Continuous variables were expressed as median(25.th-75.th percentiles) and standard deviation. Categorical variables were expressed as counts (percentages). Results: The study group consisted of 101 patients. The mean follow-up period was 8.6 ±3.8 months. Postoperative complications were: enophthalmos, 4 patients (preoperative 20 patients); diplopia, 2 patients (preoperative 17 patients); dystopia, 1 patient (preoperative 13 patients); limitation of ocular motility, 3 patients (preoperative 21 patients), and infraorbital nerve hypoesthesia, 8 patients (preoperative 56 patients). None of the patients developed infection, implant exposure or migration, worsening diplopia, or loss of vision during the follow-up period. Dsicussion and Conclusion: The study demonstrated that porous polyethylene implants in the repair of blow-out without any fixation procedure had relatively good results with few complications.
